DASH-LOCK FOB AUTOMOBILE-CLOCKS.

Specification of Letters Patent.

Application filed March 19, 1913. Serial 110. 755,541.

To all whom it may concern Be it known that I, VVrLsoN E. Poimsn, acitizen of the United States, residing at New Haven, in the county ofNew Haven and State of Connecticut, have invented a new and usefulImprovement in Dash- Looks for Automobile-Clocks; and 'I do herebydeclare the following, when taken in connection with the accompanyingdrawings and the characters of reference marked thereon, to be a full,clear, and exact description of the same, and which said drawingsconstitute part of this application, and represent, in-

Figure 1 a View partly in side elevation and partly in broken verticalsection showing my improved dash-lock for automobile clocks with thelock in its locked position. Fi 2 a corresponding view with the lock inits unlocked position. Fig. 3 a detached view in front elevation of thedash-plate. Fig. 4 a detached rear view of the clock. Fig. 5 a detachedplan view of the double key. Fig. 6 an end view of the locking-end ofthe winding key.

My invention relates to an improvement in dash-locks for automobileclocks, the object being to produce a simple and convenient lockconstructed with particular reference to accurately positioning theclock when first applied to the dash, and to preventing the clock fromworking loose under the jar of the automobile, or from being workedloose by the turning of a part of the clock or its bezel if it is akeyless clock, and winds by the rotation of its bezel or other rotarywinding-member.

With these ends in view, my invention consists in a dash lock forautomobile clocks, having certain details of construction andcombinations of parts as will be hereinafter described and pointed outin the claims.

In carrying out my invention as herein shown, I employ a circulardash-plate 2 adapted to be permanently fastened by screws 3 directly tothe dashboard 4 of an automobile. The said plate 2 is provided with anintegral positio'ningfinger 5 projecting above its upper edge andadapted the dash and whichis inclined with respect to the case-band 8 soas to give the face of the clock an upward inclination in the usualmanner as shown in Figs, 1 and 2. The said base-ring 9 is larger indiameter than the case-band 8, and also larger in diameter than thedash-plate 2, and serves to entirely Patented Oct. 21, 1913.

conceal the positioning-finger 5 thereof and the entrance of the saidfinger into the positioning notch in the rear edge 7 of the band 8, sothat when the clock is applied to the dash, the dash-plate 2 is housed,and the positioning-finger and positioning-notch are entirely concealedfrom view.

The. case-back 10 which is fixed within the rear end of the band 8 at aright angle thereto, is provided, as shown, with a heavy centrallyarranged rearwardly projecting fastening-stud 11 adapted to enter andfit snugly into an upwardly inclined socket 12 on the face of thedash-plate 2. The said socket has upon its lower edge a rib 13 having athreaded hole 13 to receive a bindingscrew 14 which enters a hole 15formed in i the lower face of the stud 11 at a right angle a triangularhead 16 which prevents it from being turned by an ordinary key andlimits its operation to a special key having a pod 17 with acorresponding triangular opening 18 as well as a pod 19 having the usualrectangular opening 20 for wlnding the clock in case a key-winding clockis used. The key shown is adouble key and formed with the usual bow 21.Access to the triangular head 16 of the binding-screw 1 1 is had througha hole 22 formed in the caseband 8 in line with the hole 15 when theclock is in place upon the dash, and normally closed by a plug 28 whichmust be removed and replaced by a screw driver.

In using my improved dash-lock, the clock is set over the plate'2 androtated with respect thereto until the notch. 6 in the band 8 snaps overthe positioning-finger 5 of the dash-plate 2, whereby the clock isaccurately positioned and thereafter prevented from being jarred looseby the jarring of the car or worked loose by the winding of the clock incase it is a keyless clock. The special key is now employed to turn thebindingscrew 14 into the hole 15 of the fastening stud 11, whereby theclock is firmly and solidly secured to the dash-plate 2. The plug 23 isnow inserted to prevent access to to the axis thereof. The said screw14: has

the screw 14 and to exclude dust from the case. For the removal of theclock from the dash 4, the plug must be first removed from the band 8after which the special key must be employed to operate the screw so asto release the stud 11 from the socket of the plate 2 from which theclock may now be drawn away.

I claim 1. In a dash-lock for automobile clocks, the combination with adash-plate provided with a positioning-finger, of a clock having itscase formed in its projecting rear edge 'ith a positioning-notch toreceive the said fingcr and provi led with a base-ring larger indiameter than the said dash-plate and band and forming a housing for thesaid plate and the rear edge of the band when the clock is fastened tothe dash, and lock ing means for permanently securing the clock-case tothe said plate.

2.1n a dash-lock for automobiles, the

combination with a dash-plate provided with a positioning-fingerand witha fastening-socket provided with a. binding-sc-rew of a clock having itsease formed in its projecting rear edge with a notch for receiving thesaid positioning-finger, and provided with a fastening-stud entering thesaid socket and bored for the reception of the said screw and the caseof the clock being also provided at its rear end with a baseflange orhousing larger in diameter than the dash-plate and case and se: ceal thedash-plate and the case when the clock is applied to in testimonywhereof, I have 1 specification in the presence of two scribingwitnesses.
